超形变扁扁超重核?

Superdeformed Oblate Superheavy Nuclei?

P. Jachimowicz, M. Kowal, J. Skalski

摘要:

我们研究了超形变扁(SDO)超重$Z\geq 120$核的稳定性,这些稳定性是在12维形变空间中通过系统的宏观-微观计算预测的,并通过Hartree-Fock计算得到证实。我们考虑了很可能以SDO形状形成的高- $K$异构体。虽然$T_{1/2}\lesssim10^{-5}$ s的半衰期是计算或估计为偶数-偶数自旋零系统,衰变障碍已知的高- $K$异构体表明,一些SDO超重核可能是可检测的本实验技术。

英文摘要:

We study stability of superdeformed oblate (SDO) superheavy $Z\geq 120$ nuclei predicted by systematic macroscopic-microscopic calculations in 12D deformation space and confirmed by the Hartree-Fock calculations with the realistic SLy6 force. We include into consideration high-$K$ isomers that very likely form at the SDO shape. Although half-lives $T_{1/2}\lesssim10^{-5}$ s are calclulated or estimated for even-even spin zero systems, decay hindrances known for high-$K$ isomers suggest that some SDO superheavy nuclei may be detectable by the present experimental technique.
